Senior cabinet minister without specific duties?

Answer 1

Lord Privy SealThe development of Cabinet left the post with little responsibility. The holder often acts as a minister without portfolio (one who does not have departmental responsibilities) and is able to undertake investigations and projects when needed by the Cabinet or Prime Minister. It is probably the earliest recognisable government post. The holder is traditionally a member of the Cabinet. Frequently the post is combined with Leader of the Commons or Leader of the House of Lords.
